Youtube promotional video

I need someone to put together a promotional video for YouTube which highlights the superior features of an engine which I have designed (see [login to view URL] for information). The aim is to attract a large audience and hopefully an investor who will finance me to put the engine into production. I will supply the material (photos, graphics and a short video clip), but the successful bidder will have to do the creative copywriting and prepare a storyboard to show how the video will be structured. A large bonus will be paid if the video successfully attracts an investor. Upon payment, I acquire full ownership and copyright of the storyboard, video and all other material produced by the successful bidder for this project. The successful bidder correspondingly agrees to destroy all copies of the materials which I have supplied and all copies the work which he/she has done.
